IMPROVEMENT IN M\CH|NES FOR BURRING WOOL AN) GINNING COTTON.

Specification forming part of Letters Patent No. 42,940, dated May 3l, 1864.

To all whom it may concern:

Be it known that JOHN GOULDING, ot' Worcester, in the count-y ot' Worcester and State ot' Massachusetts, have invented certain new and useful Improvements in Machines for Burring Tool and Ginning Cotton; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure l represents a side view of the machine. Fig. 2 represents a longitudinal vertical section through the same. Fig. 3 represents a top view ofthe machine. Fig. et represents a detached view, hereinafter to be referred to.

My invention relates to the combination of feeding, combing, and beating cylinders, b v which I effect a thorough separation of burrs or seed from the material also, in the com bination of certain devices for oiling the combing-cylinder to prevent its clogging; also, to the application of one or more partitions in the hopper to operate on di'erent staples sim ultaneously.

To enable others skilled in the art to make and use my invention, l will proceed to describe its construction and operation.

A represents the frame of the machine. B represents the hopper which receives the stock to be operated upon. (J, represented in a perspective view at Fig. 4. represents the combing-cylinder. It is a hollow cylinder provided at its circumference with comb-slats a, which carry the wool or cotton np from the hopper, a space being left between each two consecutive combs to enable them to seize the material and to permit a free passage of the dust or other impurities to the inside ot' the cylinder, which would otherwise clog up the combs.

D represents a cylinder which revolves within the hopper B and stirs up the material and keeps it in a loose condition, so as to be 'readily seized by the combingcylinder C.

E represents the burring-cylinder. It is provided with beaters b, which operate upon the stock while it is carried up by the combs of the cylinder G and beat ott' the burrs orseeds which are thrown back into the hopper B. The rear sides, g, of this hopper, which are perforated for the escape of the dust, are hung upon a cross-rod, c, and incline toward i the cylinder G, having an aperture, d, at the bottom through which the seed or burrs can escape. The size of this aperture can be adjusted by means of the rods f, by which the lower ends of the screens g can be moved to or from the cylinder C, and can be secured in their positions by means of clamp-screws h, or otherwise. Thus the size ot the passa-ge d is adjusted to insure a perfect operation of the machine according to the material to be acted upon.

m represents a spring-plate within the hopper B, which presses the material toward the combingcylinder C, and thus causes the combs to take hold of the wool or cotton. The burring-cylinder E and the spring-plate fm are both secured to the adjustable frame H, which is pivoted at k to the main frame, and the position of which can be adjusted by means of the set-screws n. 'Ihns the pressure of the spring-plate m, as well as the action ot' the buriiugcylinder E, can be adjusted with great accuracy.

F represents the stripping cylinder. It is provided with brushes o on its circumference, which strip the combs cof the stock after the burrs or seeds have been beaten oft' by the cylinder E, and the material drops down on the partition l.

It has been found by experience that the combs c on the cylinder G have a tendency to clog and become useless owing to the fibers and dust adhering to them, they not being cffectnally stripped by the Strippingvcyliuder F. To facilitate this opcration,it has been found advantageous to lubricate them with oil or grease, and for this purpose l use the following arrangement Gr represents a cylinder which revolves within a trough, K, which contains oil or other fatty substance. L represents another cylinder which is provided with onc row or set of bristles, p, which in revolving can touch the circumference of the cylinders G and C, and when the cylin ders revolve with the proper velocity the bristles p transfer the desired quantity of oil from the circumference of the cylinder G to the combs a..

The operation of the machines is as follows The cylinders and belting run in the direction ot' the arrows represented on the drawings. Motion being given to the shaft 0 ot' the cylinder C, it is communicated by belt to the pulley P of shaft q, and the pulley Q, on said sha-tt turns by means of a belt the pulley )t of roller D. rEhe pull xy S on shaft q turns the pulley T of stripper F and pulley U of the burr-cylinder E, the belt passing` over the guide pulley r on the adjustable frame H. The cylinder D runs slower than cylinder G. Burr-cylinder E runs faster than G, and so does the stripper F. The speed of the cylinder L and G must be'regulated according' to the material to be Worked, whereby the combs a may require more or less oiliug. Cylinders L and G are operated by means of pulleys XV and X, which receive their motion from pulley Z.

M represents a partition by which the hopper is divided in two compartments. A similar division or partition, N, is secured to the shield I. By means of these divisions I am enabled to operate on different staples simultaneously, as the aperture d of each screen g can be adjusted independently of the other, according to the material to be operated upon.

The front part of the spring-plate m is cut in the form ot' elongated teeth, and said. teeth are so shaped that each ot' them can spring up and down independently of the other, so as to yield should an uneven pressure be exerted upon them.

Having thus fully described the nature of my invention, what I claim herein as new, and desire to secure by Letters Patent, is-

1. The combination of the cylinders G and E with the oilingcylinders L and G, substantially' in the manner and for the purpose described.

2. The combination of the cylinders D C E F, spring-plate m, and adjustable hopperplates g, substantially in the manner and for the purpose described.

3. In combination with the adjustable hopper-plates g, the partitions M N, substantially in the manner and for the purpose described.

JOHN GOULDING.
